Parker 10343-20-20 Male Rigid Hydraulic Hose Fitting

Product Description

The PARKER 10343-20-20 is a male rigid straight hydraulic hose fitting designed for high-pressure fluid transfer applications. Built from steel, this fitting features a Female NPTF inlet paired with a Male JIC 37-degree flare outlet, providing a secure threaded connection at a 1-5/8-12 thread size. It accepts hoses with a 1.25-inch (Hose Size 20) inside diameter and measures 3.96 inches in overall length. Licensed hydraulic system technicians and industrial maintenance professionals install this fitting when terminating or connecting large-bore hydraulic hose assemblies in mobile equipment, industrial machinery, and fluid power systems.

This fitting is suited for use in hydraulic plumbing assemblies where a straight, rigid male end connection is required. The Female NPTF x Male JIC 37-degree flare shaft configuration makes it appropriate for installations transitioning between NPTF-ported components and JIC-style hose ends. It is rated for use in demanding environments where consistent sealing and mechanical integrity are critical. Both residential shop equipment and commercial-grade industrial hydraulic circuits are common installation contexts.

Installation Notes

Installation should be performed by a qualified hydraulic system technician or fluid power specialist. Depressurize and fully discharge the hydraulic system before removing or installing any fittings to prevent fluid injection injury. Use the appropriate hex wrench on the 1-7/8-inch hex to torque the fitting; consult the applicable Parker assembly specification or fluid power standard for proper make-up procedure. Verify thread engagement and inspect for leaks after system pressurization.
